In FIG. 1, the reference numeral 1, as a whole, shows a robot of the embodiment of this invention, leg units 3A–3D are connected accordingly on back and forth and right and left of a body unit 2, and a head unit 4 is connected at the front end of the body unit 2.

Here, the body unit 2 is stored of a controller 10 controlling whole motion of the robot 1, a battery 11 as a power source of the robot 1, and variety of sensors such as a battery sensor 12 and an acceleration sensor 13, and is provided with some touch sensors 14 (14A–14D) and Light Emitting Diode (LED) 15 (15A–15D), each slot (not shown in Figs.) for a dedicated memory card and a personal computer (PC) card at prescribed positions of the body unit 2.

The head unit 4 is provided with a microphone 16 representing “a ear”, charge coupled device (CCD) camera 17 representing “an eye” of the robot 1, variety of sensors such as a distance sensor 18, a face touch sensor 19, and a head touch sensor 20, and a speaker 21 representing “a mouth” at prescribed positions, as well as is provided with a free-popped-and-stored retractable headlight 22 at the top and a plurality of LED 23 around the middle-level at a regular interval.

Furthermore, knee joints of each of the leg units 3A–3D, shoulder joint connecting of each of the leg units 3A–3D and the body unit 2 respectively, a neck joint connecting the head unit 4 and the body unit 2, and an open-close driving part of the retractable headlight are provided with actuators 24 ₁–24 _(n) of degree of freedom and number as appropriate, and potentiometers 25 ₁–25 _(n) coupled with those actuators 24 ₁–24 _(n).

And, the microphone 16 of the head unit 4 collects audio inputs given from a user such as “Walk”, “Lie down”, or “Chase the ball”, and other voices and various sounds, and transmits the collected audio signals S1 to the controller 10. The CCD camera 17 pictures the surroundings to transmit the obtained image signals S2 to the controller 10, and the distance sensor 18 measures the distance to an obstacle in front to transmit the measured result to the controller 10 as a distance measurement signal S3.

Furthermore, the face touch sensor 19 detects the press operation by a user and transmits the detection result to the controller 10 as an operation detection signal S4. The head touch sensor 20, as is obvious in FIG. 1, detects that a lever oscillating-freely provided on the right side of the head unit 4 is brought down back or forth (in the direction of the arrow x or in the opposite direction), and transmits the detection result to the controller 10 as the operation detection signal S4.

In addition, the battery sensor 12 of the body unit 2 detects the remaining energy amount of the battery 11, and transmits the detection result to the controller 10 as a battery remaining amount signal 5. The acceleration sensor 13 detects the acceleration in the direction of the arrow x, y, and z of the robot 1 in FIG. 1, and transmits the detection result to the controller 10 as an acceleration detection signal S6.

Furthermore, each of the touch sensors 14 (14A–14D) provided on the body unit 2 respectively detects press operation by a user, and transmits the detection result to the controller 10 as an operation detection signal S7.

Still further, each potentiometer 25 ₁–25 _(n) detects the rotation angle of the output axis of the corresponding actuators 24 ₁–24 _(n), and respectively transmits the detection result to the controller 10 as angle detection signals S8 ₁–S8 _(n).

The controller 10 is composed as a micro computer configuration comprising a central processing unit (CPU), a read only memory (ROM), and a random access memory (RAM), and controls the motion of the robot 1 in accordance with control data such as a control program previously installed in an external memory, after-mentioned various motion files, audio files, and LED files.

In practice, the controller 10, for example when an external memory 26 stored of control data for autonomous mode (hereinafter, this is referred as a memory for autonomous mode 26A) is installed, judges the external and internal condition and whether or not a command or a contact from a user based on the audio signal S1 from the microphone 16, the image signal S2 from the CCD camera 17, the distance measurement signal S3 from the distance sensor 18, the operation detection signals S4 from the face touch sensor 19 and the head touch sensor 20 (hereafter, these are collectively referred as external information signals), and the battery remaining amount signal S5 from the battery sensor 12, the acceleration detection signal S6 from the acceleration sensor 13, and the angle detection signals S8 ₁–S8 _(n) (hereafter, these are collectively referred as internal information signals).

The controller 10 decides the following action based on the judged results and the control program stored in the memory card for autonomous mode 26A, reproduces the corresponding motion file in the motion files comprised of control data for various motion patterns stored in the memory card for autonomous mode 26A as appropriate based on the decision results, and makes various motions such as shaking the head unit 4 up and down and right and left, popping and lighting the retractable headlight 22, and making a step by driving the leg units 3A–3D, and makes a series of motions by transmitting driving signals S9 ₁–S9 _(n) based on the so obtained control data to the corresponding actuators 24 ₁–24 _(n) to be driven.

At this time, the controller 10 reproduces the corresponding audio file in the various audio files stored in the memory card for autonomous mode 26A as appropriate, and outputs the voice based on the audio signal S10 by providing the audio signal S10 so obtained to the speaker 21. In the same manner, at this time, the controller reproduces the corresponding LED file in the LED files for each flash pattern of each LED 15 of the body unit 2 and each LED 23 of the head unit 4 stored in the memory card for autonomous mode 26A, and flashes the LED 15 and 23 based on the so obtained control data with the corresponding pattern.

Herein, in the robot 1, the motions and actions corresponding to the control program stored in the external memory card 26 and each of the various data files are conducted under the control of the controller 10.

In this robot 1, each leg units 3A–3D and the head unit 4 are physically and electrically connected through a connector having standardized shape (not shown) to the body unit 2 respectively, and each leg units 3A–3D and the head unit 4 is replaceable in unit with other unit having the same connect.

In this case, when the leg units 3A–3D and the head unit 4 are set replaceable, since the moment, the default value of the joint angle and the like are different for each shape of the leg units 3A–3D and the head unit 4, respective control is required in accordance with the shape corresponding to the shape of the leg units 3A–3D and the head unit 4 to realized the same motion to be expressed by the robot 1.

Here, in this embodiment of this invention, a memory (not shown) having recognition data indicating the shape of the leg units 3A–3D and the head unit 4 inside the leg units 3A–3D and the head unit 4, as well as adjustment data for each shape for realizing the controller 10 controlling corresponding to the shape is stored in the memory for autonomous mode 26A for each of the leg units 3A–3D and the head units corresponding to the recognition data.

(4) Processing of Controller 10

Next, specific processing of the controller 10 (FIG. 2) of the robot 1 will be explained.

The controller 10 executes above-mentioned various processing based on the control program stored in the memory 10A. The processing contents of the controller 10 can be functionary classified as shown in FIG. 7, to a condition recognition part 70 for recognizing the external and internal conditions, an instinct emotion part 71 for deciding the emotion and the instinct conditions based on the recognized result of the condition recognition part 70, an action selection part 72 for deciding the following action based on the recognized result of the condition recognition part 70 and the output of the instinct emotion part 71, a learning growth part 73 for increasing or decreasing the expression probability of various actions for the next based on the decided result of the action selection part 72, a command conversion part 74 for selecting the action corresponding to the decided result of the action selection part 72 and reflecting to the robot 1 and/or the communicator 50, and a conversation control part 75 for outputting the contents of conversation based on the output of the command conversion part 74 and the condition recognition part 70.

Hereafter , the condition recognition part 70, the instinct emotion part 71, the action selection part 72, the learning growth part 73, the command conversion part 74, and the conversation control part 75 will be explained in detail.

(4-1) Construction of Condition Recognition Part 70

The condition recognition part 70 recognizes the specific condition based on the above-mentioned external information signals S1–S4 and the internal information signals S5, S6, S8 ₁–S8 _(n) in FIG. 2, and notifies the recognized results to the instinct emotion part 71 and the action selection part 72 as condition recognition information S20.

In actually, the condition recognition part 70 always monitors the image signal S2 provided from the CCD camera 17 (FIG. 2), and recognizes for example “there is a ball” or “there is a wall” with the detection of “something red and round” or “a vertical flat surface” in the image based on the image signal S2 then notifies the recognized results to the instinct emotion part 71 and the action selection part 72.

In addition, the condition recognition part 70 always monitors the audio signal S1 provided from the microphone 16 (FIG. 2) and notifies the recognized results to the instinct emotion part 71 and the action selection part 72 as well as the conversation control part 75 with a detection of input of a command sound such as “Walk”, “Lie down”, and “Chase the ball”.

Furthermore, the condition recognition part 70 always monitors the operation detection signals S4 and S7 provided from the face touch sensor 19, the head touch sensor 20, and each of the touch sensors 14 (14A–14D) (FIG. 2), and recognized a press having the threshold value or more and short (for example less than two seconds) as “I'm hit (I'm scold)” and recognizes a press having less than the threshold value and long (for example two seconds or more) as “I'm pat (I'm praised)”, then notifies the recognized results to the instinct emotion part 71 and the action selection part 72.

(4-2) Construction of Instinct Emotion Part 71

The instinct emotion part 71 stores parameters for each emotion representing the strength of the emotion of total six types “Joy”, “Sadness”, “Surprise”, “Fear”, “Dislike”, and “Anger”. The instinct emotion part 71 sequentially updates these parameter values of each emotion based on the specific recognized results such as “I'm hit” and “I'm pat” provided from the condition recognition part 70 as the condition recognition information S20, after-mentioned action decision information S21 representing the decided output action provided from the action selection part 72, and the elapsed time.

In specific, the instinct emotion part 71, computes, at prescribed intervals, the parameter value E[t+1] for the next period with the following expression E[t+1]=E[t]+k _(e) ×Δ[t]  (1) provided ΔE[t] is the emotion variation computed by a prescribed expression based on the degree (previously set) with which the recognized results obtained based on the condition recognition information S20 and the output action based on the action decision information S21 make influence to the emotion, the degree of the control and the stimulation received from other emotion, and the elapsed time, E[t] is the parameter value of the present emotion, and k_(e) is the factor representing the ratio with which the emotion is changed based on the recognized result and the like.

Then the instinct emotion part 71 makes update the parameter values of the emotion by replacing the parameter value E[t] of the present emotion with the computed result. It is predetermined which emotion's parameter value is updated for each recognized result and each output action. For example, when the recognized result “I'm hit” is provided, the parameter value of emotion “Anger” is increased as well as the parameter of emotion “Joy” is decreased, and when the recognized result “I'm pat” is provided, the parameter value of emotion “Joy” is increased as well as the parameter value of emotion “Sadness” is decreased.

In the same manner, the instinct emotion part 71 stores parameters representing the strength of four types of independent desire “Kinetic drive”, “Desire for adoration”, “Appetite”, and “Curiosity”. The instinct emotion part 71 sequentially updates the parameter values of these desire based on the recognized results from the condition recognition part 70, elapsed time and the notification from the action selection part 72.

In specific, as for “Kinetic drive”, “Desire for adoration” and “Curiosity”, the instinct emotion part 71 computes , at prescribed intervals, the parameter value for the next period I[k+1] with the following expression I[k+1]=I[k]+k _(i) ×ΔI[k]  (2) provided that ΔI[k] is the variation computed with a prescribed expression based on the output action of the robot 1, elapsed time and the recognized results, I[k] is the parameter value of the present desire of the minus, and k_(i) is the factor representing the sensitivity of the desire, then updates the parameter value of the desire by replacing the parameter value of the present desire I[k] with the computed results. It is predetermined which desire's parameter value is updated for each recognized result and each output action. For example, when the action selection part 72 notifies that an action is taken, the parameter of “Kinetic drive” is decreased.

In addition, as for “Appetite”, the instinct emotion part 71 computes, at prescribed intervals, the parameter value of “Appetite” I[k+1] with the following expression I[k]=100+B ₁  (3) provided that B₁ is the battery remaining amount based on the battery remaining amount detection signal S5 (FIG. 2) provided through the condition recognition part 70, then updates the parameter value of “Appetite” by replacing the parameter value of the present parameter value of appetite I[k] with the computed result.

In this embodiment of this invention, the parameter values for each emotion and each desire are controlled to change between 0 and 100, and factors k_(e), k_(i) are individually set for each emotion and each desire.

(4-3) Construction of Action Selection Part 72

The action selection part 72 decides the following action based on the condition recognition information S20 provided from the condition recognition part 70, the parameter values of each emotion and each desire in the instinct emotion part 71, the action models previously stored in the memory 10A, and elapsed time, then outputs the decided results to the instinct emotion part 71, the learning growth part 73, and the command conversion part 74.

In this case, the action selection part 72 takes an algorithm called automan probability which decides, as a probability, to which NODE of NODE₀–NODE_(n) a node NODE₀ (state) will transit based on the transition probability set for each of arc ARC₀–ARC_(n) connecting each of NODE₀–NODE_(n) as shown in FIG. 8.

More specifically, in the memory 10A, a state transition table 76 for each of NODE₀–NODE_(n), as shown in FIG. 9, is stored as an action model, and the action selection part 72 is configured to decide the next action based on the state transition table 76.

Here, in the state transition table 76, an input event (the recognized result of the condition recognition part 70) taken as a transit condition in the NODE₀–NODE_(n) is listed in the row “Input event”, and additional conditions for the condition is described in the corresponding column of the row “Data Name” and “Data Range”.

Accordingly, in NODE₁₀₀ defined in the state transition table 76 of FIG. 7, the fact that the “Size (SIZE)” of the ball provided with the recognized result “Ball Detected (BALL)” is in the rage of “o to 1000 range (0, 1000)”, and the fact that the “distance (DISTANCE)” to the obstacle provided with the recognized result “Obstacle Detected (OBSTACLE)” is in the range of “0 to 1000 range (0, 1000)” are the conditions for transition to the self or other node.

In this node NODE₁₀₀, with no input of a recognized result, it can transit to self or other node when the parameter value of either emotion “Joy (JOY)”, “Surprise (SURPRISE)”, or “SADNESS (SUDNESS)” is between “50 to 100 range (50, 100)”.

Furthermore, in the state transition table 76, in the column “transition target node” of “probability of transition to other node”, node names capable of being a target transited from the node NODE₀–NODE_(n) are listed, while the probability of transition to the NODE₀-NODE_(n) with all conditions described in each of row “Input Event Name”, “Data Value”, and “Data Range” met is described in the row of the node NODE₀–NODE_(n) of the column “probability of transition to other node”, and the action or motion output at that time is described in row “Output Action”. The sum of probability of transition described in each row of the column “probability of transition to other node” is 100%.

As a result, in this example node NODE₁₀₀, when the recognized results of “Ball Detected (BALL)” and the range of “0 to 1000 range (0, 1000)” for “Size (SIZE)” of the ball are provided, it can transit to “node NODE₁₂₀ (node 120)” with a probability of “30%” and the action or motion of “ACTION 1” is output.

The action model is constructed with connected number of nodes NODE₀–NODE_(n) described as the state transition table 76.

Accordingly, the action selection part 72 decides the next action or motion (the action or motion described in row “Output Action”) as a probability using the state transition table 76 of the corresponding node NODE₀–NODE_(n) of the action model stored in the memory 10A when the condition recognition information S20 is provided from the condition recognition part 70 or prescribed time is elapsed after the last expression of action.

At that time, the action selection part 72, outputs the decided action or motion to the instinct emotion part 71 and the command conversion part 74 as an abstract command (hereafter, this is referred as a LMS command) classified into three classes, large, medium, and small to which means are provided respectively.

In this LMS command, when the action decided in the action selection part 72 is “Shake Hands”, the upper class represents “Contact user”, the middle class represents “Motion of Left foreleg”, and the lower class represents “Hold at prescribed position”, and utterance text representing at least one kind of contents of the utterance is additionally described corresponding to the action.

In practice, a plurality of patterns for each kinds of the multiple action or motion selectable in the action selection part 72 (hereafter, these are referred as action pattern) is set based on the above-mentioned state transition table 76 in the LMS command, and the action pattern is stored in the memory 10A of the controller 10 as a file. For example, in the case of the action “Shake Hands”, which foreleg of right and left is to be put out is set as multiple action patterns.

In the state transition table 76, a situation ID is assigned for each of nodes NODE₀–NODE_(n). The action selection part 72 is configured to transmit a command having the situation ID representing the present node, the utterance text representing at least one contents of the utterance corresponding to the situation ID, and the tone parameter number representing the tone set corresponding to the contents of the utterance (hereafter this is referred as a sentence command) to the command conversion part 74 together with the LMS command as appropriate.

Furthermore, when a scenario ID representing a conversation request is provided from the conversation control part 75, the action selection part 72, substituting to the above-mentioned sentence command, transmits a command having two node numbers of the present node and the next transition target node, and the description of “Output Action” representing the next action or motion (hereafter, this is referred as a scenario command) together with the LMS command to the command conversion part 74, as appropriate.

(4-4) Construction of Learning Growth Part 73

The learning growth part 73 inputs the recognized result of the teaching received as a contact from the user such as “I'm hit”or “I'm pat” based on the LMS command provided from the action selection part 72.

The learning growth part 73 is configured to then change the action or motion as if a real animal “grows up” corresponding to the recognized result, the history of communication between the communicator 50, the history of self action and motion, and the active elapsed days and accumulated active hours from the initial start-up to the present.

In specific, for example five “growth steps”, “birth”, “childhood”, “boyhood”, “adolescence” and “adulthood” are set, and in the memory 10A of the controller 10, action and motion models comprised of each control parameter and control program which are the base of the action or motion relating to four items “walking state”, “motion”, “action”, and “sound (utterance, call)” for each of the “growth steps” are previously stored.

The learning growth part 73 selects one action and motion model among the each of the action and motion models for the next “growth step” based on the accumulated degree of multiple elements relating to the “growth”, then transmits the changed result to the action selection part 72 as change command information S22 after changing the action and motion model to be used to the selected action and motion model.

As above described, the learning growth part 73 can change the “growth step” as appropriate, and can reflect the action and motion model selected in the “growth step” on the action decision in the action selection part 72.

(4-4) Processing in Command Conversion Part 74

In the multiple action patterns set for each of the multiple action or motion selectable in the above-mentioned action selection part 72, an ID (Identity) is assigned for each hardware (such as actuator 24 ₁–24 _(n), speaker 21, and LED 15, 23) of the robot 1, and is mapped in the memory 10A.

For example, in this embodiment, the robot 1 is quadrupedal, and the actuators 24 ₁–24 _(n) is driven depending on each of the leg units 3A–3D, however, in an automobile type robot, the actuator is rotatingly driven depending on the multiple tires, therefore, the command conversion part 74 designates the ID corresponding to the hardware of the robot 1 even when the action pattern selected in the action selection part 72 is the same, and transmits the same to an output contents control part 57.

The output contents control part 77 reads the various control data corresponding to the hardware of the robot 1 stored in a command database 78 based on a MW command ID provided from the command conversion part 74, then provides the same to a motion reproduction part 81, a sound reproduction part 80, and a LED reproduction part 79.

As described above, the motion reproduction part 81 drives the necessary actuator 24 ₁–24 _(n) based on the driving signal S9 ₁–S9 _(n) to be a prescribed state, the sound reproduction part 80 outputs the voice based on the audio signal S10 from the speaker 21, and the LED reproduction part 79 flashes each of the LED 15 and 23 with a flashing patter based on the control data.

On the other hand, the command conversion part 74 transmits the LMS command received from the action selection part 72 to the conversation control part 75 as it is. When a sentence command or a scenario command is received with the LMS command, the command conversion part 74 transmits only the sentence command or the scenario command to the conversation control part 75.

(4-5) Processing in Conversation Control Part 75

When a LMS command is provided from the action selection part 72 through the command conversion part 74, the conversation control part 75 extracts the utterance text added to the LMS command and reads the text data corresponding to the contents of the utterance based on the utterance text from a conversation data part 82.

At this time, when there are multiple kinds of contents of the utterance based on the utterance text, the conversation control part 75 reads the text data corresponding to the contents of the utterance randomly selected from the conversation data part 82.

Then, the conversation control part 75 converts the text data corresponding to the utterance text through a session service part 83 and the following wireless communication control part 84 to a wireless data and transmits the wireless data to the communicator 50. As a result, the contents of the utterance based on the text data is displayed in accordance with the action of the robot 1 on the display of the communicator 50, for example with document data format such as extensible markup language (XML).

At this time, the conversation control part 75 has a time filter function, can prevent that multiple contents of utterance are displayed on the communicator 50 in five seconds by extracting the utterance text of the count-start (or count-end) from the LMS command when multiple LMS commands are provided in five seconds.

On the other hand, when a sentence command is received from the action selection part 72 through the command conversion part 74, the conversation control part 75 reads the text data based on the utterance text extracted from the sentence command, as well as generates musical instruments digital interface (MIDI) data file based on the tone parameter number and the data volume of the text data extracted from the sentence command.

Then, the conversation control part 75 transmits the wireless data based on the text data to the communicator 50, as well as transmits the MIDI data file to a sound reproduction part 79, so that the contents of the utterance based on the text data are displayed on the display of the communicator 50 in accordance with the action transition state of the robot 1 and an pronounced sound based on the MIDI data file is output from the robot 1, as a result, the user using the communicator 50 can be naturally on attention.

On the other hand, the conversation control part 75 transmits a scenario ID to the action selection part 72, and when a scenario command is received from the action selection part 72 through the command conversion part 74, the conversation control part 75 generates a scenario data including specific contents of utterance based on the scenario command or the recognized result using a knowledge information part 85, then displays the scenario based on the scenario data on the display of the communicator 50.

The conversation control part 75 can display the menu based on the utterance data for menu on the display part 51 of the communicator 50 by transmitting the data of utterance for menu to be displayed on the display part 51 of the communicator 50 with the same document data format as the scenario data (for example XML) to the communicator 50. As described above, the interactionable scenario utterance and the selection of menu are in the same document data format, so that the control of scenario data can be easy.

(5) Conversation with Robot 1 Using Communicator 50

In practice, in the communicator 50, the conversation control part 75 shown in FIG. 7 receives the LMS command, sentence command, or scenario command from the action selection part 72 in the above-mentioned processing of the controller 10 of the robot 1, so that three types of contents of utterance “soliloquy utterance”, “sentence utterance”, and “scenario utterance” can be displayed on the display part 51.

(5-1) Soliloquy Utterance

Soliloquy utterance is the utterance explaining the condition where the robot 1 autonomously acts, and displays, in accordance with the action of the robot 1, the contents of utterance set corresponding to the action on the display part of the communicator 50.

In specific, the above-mentioned LMS command is in the format comprised of a command and utterance text as shown in FIG. 10, and is displayed for example starting from the initial character “L”, followed by “CONTACT (contact user)”, “FLEFT(motion of left foreleg)”, “HOLD (hold at prescribed position)”, and the last character “B” when the action of the robot 1 is “Shake Hands”, and the utterance text is displayed as “Please Shake Hands” following the command.

Here, when multiple utterance text, such as “Let's Shake Hands” and “Let's hand-shake”, are added to one command, one of the utterance text is randomly selected, so that different contents of utterance can be provided to the communicator 50 even when the robot 1 repeats the same action, as a result, there can be a benefit that the user is not made to lose interest or be bored.

Other than above, for example, when the action of the robot 1 is “Lie down”, the command is displayed starting from the initial character “L”, followed by “CHGPOS (change position), “LIE (lie down)”, “NORMAL (normal position)”, and the last character “B”, and the utterance text is displayed as “alley-oop” following the command.

As described above, when multiple utterance text are provided in five seconds, the soliloquy can prevent that multiple contents of utterance are displayed on the communicator 50 in five seconds and make the user difficult to see by displaying only the utterance text of the count-start (or at count-end) on the display part 51 of the communicator 50.

(5-2) Sentence Utterance

The sentence utterance generates and displays the utterance corresponding to the state of the state transition table 76 on the display part 51 of the communicator 50 with embedding the utterance into the state transition table 76 shown in FIG. 9 as a command.

In specific, the above-mentioned sentence command, as shown in FIG. 11, is in the format comprised of a situation ID, a sub ID, text and tone parameter number (ttm-index).

As shown in FIG. 11(A), when the action of the robot 1 is “Recovery from Fall”, the situation ID is “0x00410001”, the sub ID is “1”, and the text is displayed as “I'm fell down”.

Here, where multiple sub Ids “2”–“10” are added to one situation ID “0x00410001”, the text are displayed as “Help me”, “Oops”, “I stumble over”, “I looked away”, “I had a scare”, “I can't walk”, “I fell over”, “I slipped”, and “I got a clam” respectively, and when the sub ID is directly designated, the corresponding text is displayed, however, when only the situation ID is designated, the text corresponding to one sub ID is selected randomly, so that different contents of utterance can be provided to the communicator even when the same action of the robot 1 is repeated, as a result, there can be a benefit that the user is not made to lose interest or be bored.

In addition, as shown in FIG. 11(B), when the action of the robot 1 is “Response”, the situation ID is “0x00700010”, sub ID is “1”, and the text is displayed as “I'm fine”, and when following these, the tone parameter number is displayed as “10”, the tenth tone of multiple tone previously set is selected, and the robot 1 utters the pronounced sound corresponding to the selected tone.

The tone parameter number is the tone number with which the sound is reproduced as if it is in accordance with the utterance, and which is set in accordance with the growth stage and emotion level, and is “0” without designation.

(5-3) Scenario Utterance

Scenario utterance is used for executing a scenario previously set among the robots 1 when a multiple series of utterance as a scenario is required, and displays the utterance corresponding to the scenario on the display part of the communicator 50.

In specific, the scenario data generated based on the above-mentioned scenario command or the condition recognized result in the knowledge information part 85 (FIG. 7) is, as shown in FIG. 12, in the format comprised of a node number, a conditional expression, a motion mode of the communicator 50, text, a motion command, and a following transition node number.

In specific, the text data is displayed as , for example the node number “0”, the conditional expression “if the present time is before five o'clock to communicator name”, the motion mode of the communicator “terminal mode”, the text “Good evening”, the motion command “greetings”, and the following transition node number “100”. In the conditional expression, the items between the “%” mean a variable (knowledge information), and for example, “%HOUR%” represents the present time.

In other words, the scenario based on the scenario data provides the contents of utterance “Good evening” when meeting a user having communicator name “undefined” before five o'clock to the communicator 50 while the robot executes the motion corresponding to “greetings”.

(5-4) Utterance for Menu

In addition to the above three types of contents of utterance, the utterance for menu to be displayed on the display part of the communicator 50 is transmitted in the same document data format as the scenario data (for example XML)to the communicator 50, so that there can be a benefit that the control of scenario data is easy.

For example, the utterance data in the document data format as described in FIG. 13(A) is displayed on the display part of the communicator 50 as shown in FIG. 13(B).

(6) Security Measures Realized by Communicator Registration

In the wireless communication between a plurality of robots 1 and a plurality of communicators 50, when one of the robot 1 is assigned as a master and all the other robots 1 and all the communicators are regarded as slaves, none of the slaves can communicate each other and each slave is required to make communication through the master.

At this time, there has been a problem that the communicator 50 cannot ensure the security on operation and easy connection of wireless communication when a specific communicator 50 is not registered in each robot 1.

Therefore, the communicator 50 can keep the security on operation and easy connection of wireless communication by the registration of the specific communicator 50 on the robot 1, where each robot 1 is couple with a specific communicator 50.

For example, when the robot 1 is operated, the robot 1 does not response at all to the operation on menu line by the communicator 50 which is not a registered communicator 50, so that the security on operation can be ensured.

In addition, when the robot 1 transmits the text data representing a soliloquy, only the registered communicator 50 can display the soliloquy based on the text data, so that the easy connection of wireless communication can be ensured.

(7) Transition State of Communicator 50

In actually, in the communicator 50, the display contents are read from the ROM and the RAM for program 57 or obtained from the corresponding robot 1 for variety set functions necessary for the communication between the robots 1 or the communication between the robot 1 and the communicator 50, and is displayed on the display part 51 with sequential transition of the display in accordance with each of the display contents.

At this time, the communicator 50 has different types and contents of the display transiting on the display part 51 depending on whether the communication between the robots 1 is available or not. In other words, when the communicating state between the robots 1 is off-line state (idling state), the communicator 50 as shown in FIG. 14, is configure to transit from a main menu display F1 to a name-card display F2 for acquiring name-card information from the communicating robot 1, a name-card acquisition idling display F3 for acquiring name-card information from the robot 1 whose name-card information is not acquired, a communicator display F5 for displaying that the communicating robot 1 is being connected, and a search display F6 for searching a communicatable robot 1 as appropriate.

On the other hand, when the communicating state between the robots 1 is on-line state (connected state), the communicator 50 is configured to transit from the main menu display F1 to a terminal mode display F7 for real-time chatting with the robot 1 by connecting the communicating robot 1 via the connection idling display F5, then to transit to a main menu display F8 for connected state which is like the main menu display F1 (hereafter, this is called as a connection main menu display F8).

Then, the communicator 50 transits the display from the connection main menu display F8 to a name-card display F9 targeting the robot 1 whose name-card information is acquired and a name-card acquisition impossible display F10 for displaying that the name-card information cannot be acquired, as well as to the name-card acquisition idling display F3, the communicator set display F4, and the connection idling display F5 in the same manner as off-line state.

Furthermore, the communicator 50, in the terminal mode display F7 displayed during the execution of chat, transits the display to a robot menu display F11 in accordance with the application of the robot 1 side, and the display contents of the terminal mode display F7 can be displayed as a log (a historical record of the system) even during off-line state.

(7-1) Main Menu Display F1

When the power is on with press operation of the power key 52F (FIG. 5) of the operation part 52, the communicator 50, as shown in FIG. 15, displays at first the after-mentioned search display F6 via an initial display F0 on the display part 51, and searches for a robot 1 communicatable in the neighborhood of the own robot 1 with the search display F6 displayed. Then, with the searched result after prescribed time passed, the communicator 50 transits the display from the search display F6 to the main menu display F1.

In the main menu display F1, as shown in FIG. 16(A), “Main Menu” is displayed as a title bar, and “Robot List”, “Communicator List”, and “Menu” are listed in line as menu items.

At the last line of the main menu display F1, marks showing “Search” and “Name-Card” to which the above-mentioned reserved keys 53C and 53D are assigned are displayed on the right and left, and between the marks a mark showing the connection or the disconnection of the communication, an indicator showing the remaining battery amount, and a scroll button are displayed as GUI.

Among those menu items, “Robot List” has different display contents corresponding to the searched result of the robot 1, and when communicating robots 1 are searched, the names of the robots 1 are listed for the robots 1 whose name-card information is acquired, while “Unregistered Robot” is displayed for the robots 1 whose name-card information is not acquired. On the other hand, when no communicatable robot 1 is searched, a message such as “Robot not found” is displayed as shown FIG. 16(B).

In the “Communicator List”, the names of communicators 50 coupled with the robots 1 are displayed. When communicatable robots 1 are searched, the names are listed as the names of the communicators 50 for the robots 1 whose name-card information are acquired, and “Unregistered Communicator” is displayed for the robots 1 whose name-card information are not required as the names of the communicator 50.

Further, in the “Menu”, “Communicator Set” for changing the set of various contents of the communicator 50, and “(A) Robot 1 Searching” for executing the same function as the reserved key 52C corresponding to the “Search” at the left bottom are listed and displayed.

In the main menu display F1, for the transition of the display to the display corresponding to the list items by designating the desired list item, the user is required to operate to press the cursor key 52B of the operation part 52 to adjust the position of the cursor on the desired list item, then operate to press the decision key 52A.

(7-1-1) Name-Card Display

In the communicator 50, when the main menu display F1 is displayed, and the desired robot name of the “Robot List” is selected by the cursor, and then the reserved key 52D corresponding to the “Name-Card” is operated and pressed, the display is transited from the main menu display F1 to the name-card display F2 in case that the name-card information of the robot name is already acquired.

At the left bottom of the name-card display F2, a mark showing “Back” is displayed in the place of the mark showing “Search” while the mark showing “Name-Card” at the right is deleted, and the reserved key 52C corresponding to the mark showing “Back” is assigned of the function for transmitting the display from the name-card display F2 to the main menu display F1.

Furthermore, the robot 1 can only either of select autonomous mode and sleep mode during being lifted in user's arms since the four leg units 3A–3D are not on the ground.

(8-6) Growth Set

Furthermore, when “Growth Set” is selected with the robot menu display F11 displayed on the display part 51 under the communicating state with the registered robot 1, the communicator 50 transits the display from the robot menu display F11 to a growth set display F11F1.

In this growth set display F11F1, as shown in FIG. 39, “Growth Set” is displayed as a title bar, two options, “Growth Speed”, and “Growth Reset” are displayed in the middle, and a mark showing “Back” whose function is the same as the function assigned to the corresponding reserved key 52C is displayed in the place of the mark showing “End” at the left bottom.

In this growth set display F11F1, when “Growth Speed” is selected, the display is transited to a growth speed display F11F2. In this growth speed display F11F2, “Growth Speed” is displayed as s title bar, and four steps of speed level, “Normal”, “Quick”, “Slow”, and “Stop” are listed and displayed. The display contents at the bottom of this growth speed display F11F2 are the same as those of the growth set display F11F1.

Among these speed levels, provided that “Normal” is the usual growth speed, “Quick” is set three times quicker than “Normal” and “Slow” is set three times slower than “Normal”. “Stop” means no growth, and in this case, it is configured that sideling growth (type change) does not happen as well.

In this growth speed display F11F2, when for example “Quick” is selected, the communicator 50 transmits a control signal corresponding to the speed level to the robot 1, then displays a message “confirm the change” in the place of the list display in the middle on the display and displays marks showing “No” and “Yes” to which the cursor key 52B and the decision key 52A are assigned under the message, while the mark showing “Back” in the lower part is deleted (a growth speed display F11F3).

Then in the growth speed display F11F3, when the decision key 52A is operated and pressed with the cursor key 52B being tilted to the left, a message “Good night . . . Change valid at next wake-up” is displayed, while the marks showing “No” and “Yes” are deleted (a growth speed display F11F4).

In this case, the robot 1 is configured to shutdown the communication with the communicator 50 after changing the growth speed to the speed selected by the communicator 50, then reflect the growth speed changed after the reboot.

On the other hand, when the decision key 52A is operated and pressed with the cursor key 52B being tilted to the right, it is judged that there is no growth speed change requested, and the display is transited to the former robot menu display F11 as it is.

In this growth set display F11F1, as shown in FIG. 40, when “Growth Reset” is selected, the display is transited to a growth reset display F11F5. In this growth reset display F11F5, “Growth Reset” is displayed as a title bar, a message “Communicator 50 Confirmation Required before Reset” is displayed in the middle, and a mark showing “OK” to which the decision key 52A is assigned is displayed under the message, as well as a mark showing “Cancel”whose function is the same as the function assigned to the corresponding reserved key 52C is displayed in the place of the mark showing “Back” at the left bottom.

In this growth reset display F11F5, when the decision key 52A is operated and pressed, a message “Press the right foreleg pad of Robot 1” is displayed in the place of the message in the middle (a growth reset display F11F6).

Next, when a valid detection result of the touch sensor corresponding to the right foreleg pad of the robot 1 is acquired by the user with the growth reset display F11F6 displayed, the communicator 50 transits the display to a display F11F7 where the display contents in the middle of the growth reset display are replace with a message “Press the left foreleg pad of Robot 1”.

When a valid detection result of the touch sensor corresponding to the left foreleg pad of the robot 1 is acquired by the user with the growth reset display F11F7 displayed, the display is transited to a display F11F8 where the display contents in the middle of the growth reset display F11F7 are replaced with a message “Thank you for your bringing me up till now. I have to say real good-by. I have many good memories sharing with you. This is my last dance that you loved” following the head icon corresponding to the robot 1 and a mark showing “OK” to which the decision key 52A is assigned.

Then at the beginning of the dance of the robot 1, when the decision key 52A is operated and pressed in this growth reset display F11F8, a message “Confirm Reset” is displayed in the place of the message in the middle, and marks showing “No” and “Yes” to which the cursor key and the decision key 52A are assigned are displayed under the message as well as the mark showing “Back” in the lower part is deleted (a growth reset display F11F9).

Then, in the growth speed display F11F9, when the decision key 52A is operated and pressed with the cursor key 52B being tilted to the left, a message “Good-by. It will be reset at next wake-up” is displayed in the place of the message in the middle and marks showing “No” and “Yes” are deleted (a growth speed display F11F10)

In this case, the robot 1 shuts down the communication between the communicator 50 as well as resets various data contents after the end of the dance, so that the growth starts from a new growth process (starting from “Birth” of the growth steps” at the reboot by the user.

At this time, the robot 1 resets the data contents such as growth result, learning result, emotion/instinct value, and name-card information, and does not reset the data contents such as picture result taken and communicator registration.

On the other hand, when the decision key 52A is operated and pressed with the cursor key 52B being tilted to the right, it is judged that the growth reset is not requested, and the robot 1 stops dancing and the display is transited to the robot menu display F11 as it is.

(9) Relation between Emotion and Instinct, and Display Contents of Communicator 50

Next, the relation between the expression of the emotion and the instinct of the robot 1, and the contents of the pictographic characters P1 (FIG. 41(B)) displayed on the display part 51 of the communicator 50.

In this communicator 50, pictographic character data representing approximately one hundred kinds of unique pictographic characters are previously stored in the ROM and the RAM for program 57, the pictographic character data corresponding to the most suitable pictographic character P1 is selectively read out based on the action decision information S21 (FIG. 7), and the pictographic character based on the pictographic character data is displayed on the display of the display part 51.

In other words, in this robot 1, as above-mentioned, in the action selection part 72, which is one of the functions of the controller 10, the following action and motion are decided based on the corresponding sate transition table 76 (FIG. 9).

The action selection part 72, when a recognized result “I'm pat (PAT)” is provided from the condition recognition part 70, as above-mentioned, decides the probability of the following action and motion using the state transition table 76, and outputs the decided action and motion as the action decision information S21 to the command conversion part 74 while the action selection part 72 reads the parameter value of “Joy” in the instinct emotion part 71 and notifies it to the command conversion part 74.

Accordingly, the command conversion part 74 makes action expressing designated “Joy” by indirectly driving the necessary actuators 24 ₁–24 _(n) (FIG. 2) based on the action decision information S21 provided from the action selection part 72, as well as it displays a pictographic character P1 representing smile corresponding to “Joy” on the display part of the communicator 50 by transmitting the action decision information S21 to the communicator 50. Accordingly, the communicator 50 can express emotion “Joy” as a look as if the robot 1 is laughing in accordance with displaying the emotion “Joy” on the display part.

Furthermore, the action selection part 72, when a recognized result “I'm hit (HIT)” is provided from the condition recognition part 70, as above-mentioned, decides the probability of the following action and motion using the state transition table 76, and outputs the decided action and motion as the action decision information S21 to the command conversion part 74 while the action selection part 72 reads the parameter value of “Anger” in the instinct emotion part 71 and notifies it to the command conversion part 74.

Accordingly, the command conversion part 74 makes action expressing designated “Anger” by indirectly driving the necessary actuators 24 ₁–24 _(n) (FIG. 2) based on the action decision information S21 provided from the action selection part 72, as well as it displays a pictographic character P1 representing fierce face corresponding to “Anger” on the display part of the communicator 50 by transmitting the action decision information S21 to the communicator 50.

Accordingly, the communicator 50 can express emotion “Anger” as a look as if the robot 1 is getting angry in accordance with displaying the emotion “Anger” on the display part 51.

As described above, in the communicator 50, it is configured that the robot 1 expresses the motion such as “Joy” to “I'm pat” or “Anger” to “I7m hit” as action or motion as well as the most suitable pictographic character expressing the emotion corresponding to “Joy” or “Anger” is displayed on the display of the display part 51.

The above embodiment describes the case where a pictographic character P1 corresponding to two emotion “Joy” and “Anger” is displayed on the display part of the communicator 50, however, the present invention is not only limited to this and also other emotion such as “Sadness”, “Surprise”, “Fear”, and “Dislike” may be displayed with the most suitably corresponding pictographic characters, in addition, instinct such as “Kinetic drive”, “Desire for adoration”, “Appetite” and “Curiosity” may be displayed as a most suitably corresponding pictographic character P1.

(10) Exchange of Name-Card Information

The method for exchanging the name-card information between the robots 1 or between the robot 1 and the communicator 50 when a short distance wireless communication such as Bluetooth is used for wireless communication between the robots 1, or between the robot 1 and the communicator 50 will be explained.

For example, in the wireless communication between the robot 1 and the communicator 50, the master robot 1 is configured to exchange the name-card information between the slave communicator 50 as a connect sequence through a synchronization establishment phase and a communication connection phase complying with the connection procedure of Bluetooth.

At first, at the synchronization establishment phase, as shown in FIG. 42, the master robot 1 transmits an IQ packet to non-specific targets. The communicator 50 to be a slave transmits a frequency hopping sequence (FHS) packet to the master robot 1 as an attribute notice at the reception of the IQ packet.

The master robot 1 transmits an ID packet for confirmation to specify the communicator 50 to be a slave at the reception of the FHS packet.

As a result, the master robot 1 transmits the FHS packet as an attribute notice to the slave communicator 50 when the ID packet is transmitted from the slave communicator 50 as the response.

Then, the master robot 1 can realize so-called synchronization establishment which synchronizes the change timing of the frequency hopping in the spread spectrum system adopted in Bluetooth between the slave communicator 50 at the reception of the ID packet returned from the slave communicator 50.

Following above, in the communication connection phase, as shown in FIG. 43, the master robot 1 makes encryption each other according to the prescribed encryption procedure when the certification is possible between the slave communicator 50, while it moves to the idling phase when the certification is impossible.

Then after the encryption, the master robot 1 becomes data transmission-able state between the slave communicator 50, and executes the connect sequence as shown in FIG. 44 focusing on the exchange of the name-card information.

In this connect sequence, the master robot 1 at first searches or requests a service list (a list of available functions) on or to the slave communicator 50, then waits for the notification from the slave communicator 50 notifying the list of available functions.

Following above, the master robot 1 selects the desired service in the service list obtained from the slave communicator 50, and transmits a service request to the slave communicator 50. The slave communicator 50, based on the request from the master robot 1, responses to tell whether the service is available or not.

Then, the master robot 1 exchanges the name-card information of the robots between the slave communicator 50.

The name-card information is comprised on a SCARD where the information for the connection and control in the system layer is described in binary format, and a ACARD where the name-card contents of the robot 1 determined for each application is described in text format (XML).

In specific, in the SCARD, a device category of Bluetooth represented by “BtDeviceCategory”, a Bluetooth address represented by “BtAddress”, a name represented by “Btname”, a type of icon represented by “icon ID”, and a language represented by “BtLang” are described in binary format. In the ACARD, “ERF-310AW10” representing the type of the robot 1, “New Born Robot” representing the information, and “Sweet Latte” representing the comment are described in text format.

In practice, the master robot 1 transmits the self SCARD to the slave communicator 50, and waits for the response from the slave communicator 50 notifying of the reception.

Following above, the master robot 1 requests the SCARD of the communicator 50 to the slave communicator 50, and waits for the transmission of the SCARD from the communicator 50.

Furthermore, the master robot 1 transmits the self ACARD to the slave communicator 50, and waits for the response from the slave communicator 50 notifying of the reception.

Following above, the master robot 1 requests the ACRAD of the communicator 50 to the slave communicator 50, and waits for the transmission of the ACARD from the communicator 50.

As described above, the master robot 1 makes data communication between the slave communicator 50 corresponding to various applications after exchanging the name-card information, then returns to FIG. 43 and disconnects the communication between the slave communicator 50 when the communication is requested to be end.

(11) Conversation Sequence between Robots 1

In FIG. 45, the robot 1 confirms whether there are other robots 1 or communicators 50 in the neighborhood by transmitting IQ packets at prescribed intervals (for example every thirty seconds). When there is a robot 1 or a communicator 50 responding to the IQ packet, the master robot makes synchronization establishment with the robot 1 and the communicator 50 treating them as a slave.

Following above, the robot 1 executes a connect sequence including the exchange of the name-card information after the connection certification followed by the encryption with the slave robot 1 and the slave communicator 50.

Then the master robot 1 requests a scenario ID representing a conversation request only to the slave robot 1 (the communicator 50 is not targeted). The slave robot 1 searches into the self scenario database (the above-mentioned knowledge information part 85 in FIG. 7) whether the scenario ID obtained from the master robot 1 is responsible or not, and makes a response indicating OK if responsible.

Then,the master robot 1 transmits the scenario for example “Utterance 1” to the slave robot 1 as a text data as well as transmits the same to the slave communicator 50 when the slave communicator 50 is communication connected.

The slave robot 1 and the slave communicator 50 select “Utterance 2” in accordance with the scenario based on the text data provided from the master robot 1, and transmits the selected “Utterance 2” to the master robot 1 in the form of text data.

The master robot 1 transmits the “Utterance 2” based on the received text data to the communicator 50 when the slave communicator 50 is communication connected. Then, the master robot 1 transmits a request for end of the conversation by a scenario to the slave robot 1, so as to end the current connect sequence at the reception of the response from the slave robot 1.

As described above, when the robots 1 are communication connected each other, the conversation sequence by a scenario becomes possible, and there is a communicator 50 which is connected between the robots 1, the communicator 50 can receive from the master robot 1 and display the contents of the conversation by a scenario on the display part.

(12) Scenario Execution by Voice Recognition

When the master robot 1 autonomously connects and communicates with the other slave robots 1 and the slave communicators 50, the master robot 1 executes the scenario and communication connects to the slave robots 1 and the slave communicators 50 based on the user's operation result on the communicator 50, the recognized result of the user's voice, and the recognized result of the user's face, so that the interaction (interactive action) between the user using the communicator 50 and the robot 1 is enhanced.

(12-1) Execution of Scenario between Robots 1

At first, when two robots 1 are communication connected, the master robot 1 autonomously executes a scenario corresponding to the external circumstances after executing a scenario such as greetings toward the slave robot 1.

At this time, when the user pronounces the word “Friend” aiming to see the conversation scenario between the robots 1 by using the communicator 50, the master robot 1 can display the scenario on the display part 51 of the user's communicator 50 by autonomously executing the scenario toward the slave robot 1 based on the voice collected through the microphone 16.

On the other hand, when the word “Friend” is pronounced from the user with the robot 1 whose communication is unconnected each other, the master robot 1 transmits an IQ packet to search a slave robot 1 around, and when a slave robot 1 is not searched within a prescribed time (for example in thirty seconds), the master robot 1 notifies the result by making action for notifying the result.

As described above, the user can see the scenario in the display part of the self communicator 50 by making the master robot 1 execute the scenario by ejaculating a specific word when the user wants to see the scenario conversation between the robots 1. In addition, even when the communication between the robots 1 are not connected, the user can easily recognize that the robot 1 is not connected since the master robot 1 makes the action for notifying that fact.

In practice, in the master robot 1 under the communication connection state with other, robots in the above-mentioned FIG. 7, when the condition recognition part 70 in the controller 10 recognizes the command sound “Friend” and provides the recognized result to the conversation control part 75, the conversation control part 75 generates the scenario data based on the recognized result using the knowledge information part 85, so as to execute the scenario.

Then the conversation control part 75 can display the scenario based on the scenario data on the display of the communicator 50 by transmitting the scenario data through the session service control part 83 and the wireless communication control part 84 to the communicator 50.

On the other hand, in the master robot 1 under the communication disconnected state with other robots, the condition recognition part 70 in the controller 10 recognizes the command sound “Friend” and provides the recognized result to the conversation control part 75, and the conversation control part 75 transmits the IQ packet to outside through the session service control part 83 and the wireless communication control part 84.

Then, when the communication connection result cannot be obtained from the condition recognition part 70 after prescribed time passed, the conversation control part 75 notifies that fact to the action selection part 72, so that the action selection part 72 can decide the prescribed action or motion representing the communication disconnected and makes the robot express the corresponding action or motion.

(12-2) Execution of Interaction Scenario

The scenario with which the robot 1 talks to the user using the communicator 50, such as “How are you? <Yes> <No>”, is called as an interaction scenario. A case where the voice from the user is recognized, a case where the face image of the user is recognized, a case where the user's hand is detected, and a case where there is an input from the communicator 50 can be a trigger for making the robot 1 execute the interaction scenario since the high possibility of user existence is preferable as a trigger.

Particularly, when the interaction scenario is executed by a voice recognition, it is convenient that the voice from the user is decided to a specific language such as “Let's talk”, which allows the user to use it consciously.

In specific, in the robot 1, in the above-mentioned FIG. 7, when the state recognition part in the controller 10 recognized the command sound “Let's talk” and provides the recognized result to the conversation control part 75, the conversation control part 75 generates a scenario data representing the interaction scenario based on the recognized result using the knowledge information part 85, so as to execute the interaction scenario.

Then in the conversation control part 75, the scenario data is transmitted to the communicator 50 through the session service control part 83 and the wireless communication control part 84, so that the interaction scenario based on the scenario data can be displayed on the display of the communicator 50.

(12-2) Connection to Communicator

When the robot 1 autonomously acts, the user may want the self communicator 50 to display the soliloquy of the robot 1 by connecting the communicator 50 with the robot 1. Therefore, when the user pronounces the voice “Robot Chat” and the robot 1 recognizes this voice, the communication connection between the communicator 50 is established as well as the soliloquy from the robot 1 is displayed on the display part of the communicator 50, so that the user can easily make communication with the robot 1 to strengthen a sense of community.

In practice, in the robot 1, in the above-mentioned FIG. 7, the state recognition part in the controller 10 recognizes the command sound “Robot Chat” and provides the recognized result to the conversation control part 75, the conversation control part 75 transmits the text data corresponding to the utterance text added to the LMS command through the session service control part 83 and the wireless communication control part 84 to the communicator 50, so that the contents of utterance of the utterance text based on the text data can be displayed on the display of the communicator 50.

(13) Battery Save

The communicator 50 is a mobile equipment and the battery charge amount is consumed quickly if it is always connected, and it can be considered that the communication connection between the robot 1 is automatically disconnected after, for example, five minuets no operation by the user due to user's disregard.

However, it is not desirable to disconnect the communication connection between the robot 1 because the user doe not operate the communicator 50 for prescribed time, which is the operation against the user's intention, since it may be the case that the user only sees the robot 1 and not disregards the robot 1.

Therefore, the controller 10 of the robot 1 can minimize the consumption amount of the battery of the communicator 50 under the communication connection and at the same time can deal with the user's intention by executing the battery save processing procedure RT1 as shown in FIG. 46.

In specific, in the battery save processing procedure RT1, the controller 10 of the robot 1 enters step SP0 at the end of the operation of the communicator 50 by the user under the communication connection between the communicator 50, and waits first ten minuets continuation of the connection in the following step SP1.

Then the controller goes to step SP2 and displays contents of utterance such as “Are you bored? <Yes> <No>” on the display part 51 of the communicator 50 by executing the above-mentioned interaction scenario, then goes to step SP3.

In this step SP3, the controller 10 judges whether there is a response from the communicator 50 or not, and, with a negative judged result, goes to step SP4 where the communication connection between the communicator 50 is reconnected after two minutes disconnection.

On the other hand, the controller 10 regards a positive result at step SP3 as a response from the user, and returns to step SP2 and repeats the same process with extending the connection for five more minutes.

Following above, at step SP6, the controller 10 displays the contents of utterance based on the above-mentioned interaction scenario on the display part of the communicator 50 right after the reconnection, then goes to step SP7.

At this step SP7, the controller 10 judges whether there is a response from the communicator 50 or not, and goes to step SP8 with a negative judged result and reconnects the communication connection between the communicator 50 after four minutes disconnection.

On the other hand, the controller 10 regards a positive result at step SP7 as a response from the user, and returns to step SP2 and repeats the same process with extending the connection for five more minuets.

Following above, at step SP10, the controller 10 judges whether there is a response from the communicator 50 or not right after the reconnection, then, with a negative results goes to step SP11 where the communication connection between the communicator 50 is reconnected after six minuets disconnection.

On the other hand, the controller 10 regards a positive result at step SP10 as a response from the user, and returns to step SP2 and repeats the same process with extending the connection for five more minuets.

Following above, at step SP12, the controller 10 displays the contents of utterance based on the above-mentioned interaction scenario on the display part of the communicator 50 right after the reconnection, then goes to step SP13.

At this step SP13, the controller 10 judges whether there is a response from the communicator 50 or not with a negative judged result, and returns to step SP11, and repeats the loop SP11-SP12-SP13 until acquisition of a positive result at step SP13.

In practice, when the communicator 50 is not operated at all for five minutes, it is configured that the power is automatically shut down. When the robot 1 keeps disconnection of the communication connection between the communicator 50 for six minutes at the above-mentioned step SP11, the process is ended.

However, when the user requests the display of the communicator 50 during the robot 1's disconnection of the communication connection between the communicator 50, for example when the user pronounces the voice “Robot Chat”, the communication connection between the robot 1 and the communicator 50 is established.

In the manner as described above, even when the communicator 50 is under the communication connection state between the robot 1, the consumption amount of the battery can be minimized while the user's intention is regarded based on the robot 1's talking to.

(14) Wireless Communication between Robots

(14-1) Communication Target Direction Specifying Method During Wireless Communication

When the robots 1 make wireless communication each other, and for example when one of or both robots 1 use a non-directional antenna terminal, it is difficult for a third party to specify the direction in which the communication target exists. Also, even under wireless communication, it is difficult to recognize whether they are under communication or not.

To solve above, the direction in which the communication target exists can be specified and the face can be turned to that direction, with arrangement to receive the sound and infrared radiation obtained from the surroundings under communicating state after the establishment of the communication. For example, the sound collection condition of the microphone 16 (FIG. 2) can be changed by turning the self neck with the communication target making a sound.

(14-2) Distance to Communication Target Specifying Method During Wireless Communication

Furthermore, when the robots 1 make wireless communication each other, the distance to the robot 1 can be specified by the way where one of the robots 1 generates a prescribed sound with enough strength for practical use and the other robot 1 measures the time difference and the damping degree of the sound and executes a prescribed computing processing under communicating state.

(14-3) Communication between Multiple Languages

Furthermore, in the communication between the robots 1, the robot 1 which receives data transmitted as common data representing a command and/or a semantics having meanings as communication contents from the other robot 1, so as to recognize the contents transmitted from the other robot 1 based on the data.

As described above, between the robots 1, a command and/or a semantics independent to language are exchanged, which is different from the simple exchange of sound, so that it can pretend as if the communication between different languages (in other words, multiple languages) is established.

(14-4) Method for Recognizing Conversation between Robots

Furthermore, when the robots 1 make conversation each other, not only the wireless communication, but also the pronunciation of the voice in ordinary language is made so that the contents of the conversation can be notified to both users of the robots 1.

In other words, the actual conversation between robots 1 is made by exchanging the text data representing the contents of the conversation, the common data representing the above-mentioned command and/or semantics, and the action decision information S21 (FIG. 5) representing the emotion and/or instinct using the wireless communication means (wireless LAN card 41) which both robots 1 have, while with synchronizing the timing of transmitting and receiving each data, in each of the robots 1, a prescribed sound is pronounced from the speaker 21 (FIG. 2) of the head unit 4, the LED 15 and 23 (FIG. 2) of the head unit 4 and the body unit 2 are lightened with a prescribed pattern, and the head unit 4 and the leg units 3A–3D are moved with a desired pattern.

At this time, sound information is not used for the recognition of the conversation between robots 1, but the recognition of the contents of the conversation is made based on the data of wireless communication, and sound information and other information are used for notification to the user.

(14-5) Reception of Motion Data via Wireless Communication

When the robots 1 make wireless communication each other, when the communicating robot 1 has motion files representing motion patterns and action patterns which the self robot 1 does not have, those motion patterns and action patterner based on those motion files can be regularly used if those motion files are stored in the memory card for autonomous mode 26A by those motion files transmitted from the communicating robot 1.

In other words, when conversation in accordance with a specific scenario is made between multiple robots 1, and the robot 1 of conversation target does not have the corresponding scenario, and motion, the scenario and motion are transmitted to the target before the start of the conversation via wireless communication. As a result, by exchanging scenarios and motions between the robots 1, trendy words, relation between a teacher and a student, and growth resulted by communication can be simulated in a group composed of multiple robots 1.

Here, the above-mentioned scenario is a script or a playbook in which the order of the situation, words, and motions are described under the communicating state among multiple robots 1, and the conversation contents are prescribed according to the number of the conversation participants.

(14-6) Name-Card Exchange between Robots

When the robots 1 make conversation each other, each of the robots 1 is required to have a mechanism for recognizing each unit, therefore, when the robots 1 are communication-able state via wireless communication each other, the robots 1 exchange the name-cards in which the name, character, and the owner name are described, as a preparation step before the conversation, so that they can recognize whether it is the first meet or they meet often (friends) as well as changes can be given to the communication between the robots 1.

(15) Communication between Robot and Wireless Terminal Device

(15-1) Recognition of Owner

In the wireless communication between the robots 1, for example when a short distance wireless communication such as Bluetooth is used, the existence of the communicator 50 corresponding to the robot 1 can be known as well as the user having the communication 50 (hereafter, it is referred as an owner) can be specified at the establishment of communication between the robots 1.

Therefore, in each robot 1, if the communicator 50 connected most frequently and for the longest time is memorized together with the owner's name, and the learning effect that the owner is automatically recognized for each communication from the next time is given, the communication more close to the human relations can be realized.

In specific, the robot 1 acts a motion making the owner happy with the owner's approaching, while the robot 1 acts a motion of hesitating a little bit and a motion of having a great curiosity with an unknown user's approaching, so that the robot 1 can recognize the owner as a special person as if the robot 1 is a real animal, and the bonds between the owner can be strengthened.

(15-2) Owner Registration

In the registration system which requires password input from the communication 50 for the registration of the user under the situation where only the communication 50 can control the corresponding robot 1, when the password is leaked, it is very difficult to protect an illegal registration by a third part having no usage right.

Therefore, in the robot 1, the registrator transmits a motion approaching to the robot 1 as command contents to the communicator 50, and displays the same on the display part 51 of the communicator 50. The registrator makes the corresponding reaction approach to the robot 1 according to the displayed command contents, and only when the fact that the right reaction is executed is transmitted from the robot 1 to the communicator 50, the registrator of the communicator 50 is officially registered as an owner.

For example, when a command to touch the touch sensors 14,19,20 (FIG. 2) or a sound command is transmitted from the robot 1 to the communicator 50 as command contents, the fact that a right reaction has taken is transmitted from the robot 1 to the communicator 50 with the registrator's approaching to the robot 1 right away and touching the robot 1 or reading the sound based on the sound command, then the registrator is officially registered as an owner.

As a result, the user making the owner registration always needs to approach the robot 1 close enough to touch the robot 1, so that an illegal registration by a third party can be prevented. In addition, the user officially registered as an owner is periodically required to update the registration as occasion demands by changing the command contents transmitted from the robot 1 to the communicator 50, so that the security can be enhanced.

(15-3) Device for Displaying Conversation between Robots

When the robots 1 makes conversation (exchanges information) via wireless connection, it is very difficult to know the contents of the conversation from outside. To solve the problem, the contents of the conversation are displayed on the communicator 50 carried by the user with synchronizing the timing of the information exchange between the robots 1 as a readable text data, so that the user can know the contents of the conversation between the robots 1 by using the communicator 50.

(16) Communication with Robot 1 Using Personal Computer

(16-1) Method for Synchronizing Motions of Multiple Robot Units

At first, the motion sequence is transmitted to each of the multiple robots 1 via wireless communication using the personal communicator 31 (FIG. 3) owned by the user. In the motion sequence, the timing at which the motion after the reception of the prescribed synchronization signal, and the motion are described.

Next, the personal computer 31 transmits the synchronization signal to each robot 1 via wireless communication corresponding to the timing of music played, then each robot 1 received this synchronization signal can execute the motion based on the motion sequence, so that the motion of each of the multiple robot 1 can be synchronized.

Here, as an another method, when one of the robots 1 transmits the synchronization signal to the other robots 1 around corresponding to the timing of music played with multiple robots 1 under wireless communication-able state, each robot 1 received this synchronization signal can execute the motion based on the motion sequence same as the transmitting source robot 1, so that the motion of each of the multiple robot 1 can be synchronized.

(16-2) Method for Making Narration by Synchronizing Robot with Personal Computer

At first, the sound data representing the narration is transmitted to the personal computer 31 (FIG. 3) via wireless communication to multiple robots 1. The narration based on the sound data is comprised of sound information such as general contents of conversation and a call.

Next, the personal computer 31 transmits a synchronization signal to the robot 1 at the same time as outputs the same voice as the sound output from the robot 1, so as to make the robot 1 output the voice. As a result, the personal computer 31 can output the voice which is the same as the voice output from the robot 1 with a high quality thanks to the no motion noise of the robot 1 mixed, comparing with the case where the voice output from the robot 1 is collected directly through the microphone.

(16-3) Notification of Mode at Robot

When the robot 1 has a plurality of motion modes, the user can select a motion mode through the personal computer 31. At that time, the robot 1 can notify the reception of the motion mode to the user having the personal computer 31 by changing the data of the motion mode transmitted from the personal computer 31 to the robot 1 via wireless communication to audio data and by outputting voice based on the audio data.

As a result, the user having the personal computer 31 can recognize that the robot 1 received the motion mode selected by the user by the voice pronounced from the robot 1 even when the motion mode display function is not installed in the personal computer 31 or the display ability is low.

(16-4) Method for Chat with Picture by Multiple Robots

When each of the multiple robots 1 has the CCD camera 17 (FIG. 2) and these multiple robots 1 and the personal computer 31 (FIG. 3) are connected via network each other, the persona computer 31 can display the picture image which the robots 1 are seeing on the display can be displayed. In addition, a desired conversation sentence can be input from the personal computer 31 through the keyboard or the mouse, so that the above-mentioned chat between the robots 1 can be executed with picture images.

(17) Operation and Effects of the Embodiments

According to the foregoing construction, the above-mentioned communicator 50 for remote-control is provided corresponding to the robot 1, and the communicator 50 is configured to be connectable to the robot 1 via short distance wireless communication such as Bluetooth.

When the multiple robots 1 make conversation each other under communication-able state, when one of the robots 1 transmits a common data representing a command and/or a semantics as the contents of the conversation to other robot 1, the robot 1 which received the data can recognize the contents transmitted from the other robot 1 based on the data, and can easily exchange the contents of the conversation as well as the communication can be established even between different languages.

In practice, when the multiple robots 1 execute the communication, as shown in FIG. 47(A)–FIG. 49, the central robot 1 (such as a chairman) searches a communicatable robot 1 or a communicator 50 around (FIG. 47(A)). Then the chairman robot 1 collects the name-card (the name of the owner, name and character of the robot 1 itself) of the communicating robot 1 and the communicator 50 (FIG. 47(B)). Then the chairman robot 1 lists up the name-card, and distributes the list to the member robots 1 and communicators 50 contributing to the conversation (FIG. 48(A)). Then the chairman robot 1 starts the conversation between the member robots 1 and communicators 50 (FIG. 48(B)). Here, the chairman robot 1 can decide the order of the conversation if necessary (FIG. 49). For example, whether they want to talk to or not can be asked sequentially at a prescribed time interval.

In this manner, natural communication such as enjoying conversation between the robots 1 and the owner's understanding the thoughts and body languages of the robot 1 by using the communicator 50, can be realized.

Furthermore, with multiple robots 1, community making, such as the owner's getting together bringing their own robots 1, and the owner's making friends with the other owners, can be enjoyed.

Furthermore, as the expression of the robot 1 is displayed on the display of the communicator 50 owned by the owner, much more variations can be realized comparing with the expression by sound. In this case, the robot 1 itself can make soliloquy, be on the scrounge, can complain to the owner, response to the action of the owner, and send a quiz, riddle, fortune telling, and word of the day.

Furthermore, when the robots 1 make conversation each other, the contents of the conversation are transmitted and received not only as above-mentioned command and/or semantics but also as text data via wireless communication as well as the action decision information representing the emotion or instinct synchronizing the same,so that the contents of the conversation can be displayed as text sentence on the communicator 50 as well as the degree of the emotion and/or instinct can be displayed as pictographic characters.

Still further, under the communicating state between the robots 1, the motion files representing the motion patterns and action patterns hold by one of the robots 1 can be transmitted to the other robots 1 via wireless communication with synchronization, the robot 1 can regularly use the motion patterns and the action patterns based on the motion files as its own. As a result, in multiple robots 1, cooperating motion such as dance or imitating can be executed.

Still further, when short distance wireless communication such as Bluetooth is used as wireless communication between the robots 1, or between the robot 1 and the communicator 50, the master robot 1 exchanges the name-card information between the slave robot 1 or the slave communicator 50 as a connect sequence through the phases of the synchronization establishment phase and the communication connection phase in accordance with the Bluetooth connection procedure, so that the name-card information exchange between the robots 1 or between the robot 1 and the communicator 50 in the area of communication can be easily and naturally conducted with no user's operation.

Furthermore, when there is a communicator 50 connected those coupled robots 1 which are communication connected each other and are under the conversation sequence-able condition based on a scenario, the communicator 50 receives the contents of the conversation based on the scenario from the master robot and displays the same on the display part, so that the joy of giving a glimpse into the world of the robots 1 can be obtained.

Furthermore, when the master robot 1 autonomously connects to and communicates with the other slave robot 1 or the slave communicator 50, the master robot 1 exercises a scenario on or makes communication connection with the slave robot 1 or the slave communicator 50 based on the user's operation on the communicator 50 or the recognized result of the sound which user uttered or the recognized result of the user's face, so that the interaction (interactive action) between the user using the communicator 50 and the robot 1 can be enhanced.

For example, when the user wants to see the scenario conversation between the robots 1, the user only needs to pronounce a specific word to make the master robot 1 autonomously execute the scenario which is displayed on the display part of the self communicator 50, so that the user can easily obtain the joy of giving a glimpse into the world of the robots 1 by the user's own intention at any time.

Furthermore, the robot 1 makes the communication 50 used by the user display the interaction scenario when the robot 1 recognizes the user by the recognized result of the face image, voice, and hand contact of the user, and input from the communicator, the user can obtain surprise and joy as if a human is talking to the user.

Still further, the user connects self communicator 50 to the robot 1 by approaching with a prescribed utterance and operation on the communicator 50 on which the soliloquy of the robot 1 is displayed during the robot 1's autonomously operating, so that the user can easily make communication with the robot 1 to strengthen the sense of community.

When the robot 1 transmits the text data of the contents of utterance to the communicator 50, if the robot 1 itself pronounces the contents of utterance through the speaker 21 based on the audio data related to the text data, the user having the communicator 50 can not only see the contents of utterance displayed on the display part 51, but also hear the voice which the robot 1 pronounces, so that sense of satisfaction and community can be given to the robot 1 all the more.

Furthermore, the robot 1 under the communication connection state with the communicator 50 repeats disconnection or reconnection of the operation condition of the communicator 50 at prescribed intervals and displays the operation state on the communicator 50 for each time, so that the battery consumption of the communicator 50 can be minimized while the user's intention is regarded.

Still further, the communicator 50 is registered on the robot 1 one on one, so that the operational security and easy. connection of wireless communication can be ensured as for the communicator 50.

Furthermore, the robot 1 conducts three types of utterance, “soliloquy utterance” representing that the robot 1 is autonomously operating, “sentence utterance” corresponding to the sate transition of the robot 1, and continuing utterance “scenario utterance” based on the prescribed scenario when the robot 1 displays the utterance text on the communicator 50 under communicating state, as well as the contents of the utterance correspond to the action of the robot 1, so that a sense of satisfaction can be given to the user by expressing the robot 1 as a life like thing all the more.

At that time, in the communicator 10 of the robot 1, a command is generated with the contents of utterance being set in accordance with the state transition table 76 which is used for selecting the action of the robot 1, so that the contents of utterance corresponding to the action of the robot 1 can be easily provided to the communicator 50 without a complicated hard ware newly installed.

Furthermore, a plurality of contents of utterance corresponding to the action of the robot 1 are prepared, and these contents of utterance are randomly selected, so that different contents of utterance can be provided to the communicator 50 for each time even when the same action of the robot 1 is repeated. Therefore the user is not made lose interest or made bored.

According to the foregoing construction, in the robot 1 system, the communication 50 for remotely controlling the robot 1 is provided, and the contents of the conversation comprised of commands and semantics are exchanged between multiple robots 1 under communication-able state via wireless communication as well as the motion of motion and/or action is exchanged to be executed by itself and the contents of the communication are displayed on the communicator 50 if necessary, so that communication such as human relations can be realized between the robots 1, and an improved entertainment property can be provided.
